autofac with asp.net webforms Instances cannot be resolved and nested lifetimes cannot be

Autofac does its session disposal through an HttpModule called Autofac.Integration.Web.ContainerDisposalModule.

You need to either

• Put your own session cleanup in a module that is run before the container disposal. This can be a problem as the order of HttpModules is not guaranteed.

OR

• Remove the Container disposal HttpModule from the web.config and do your own lifetime scope cleanup in your Application EndRequest

private void Application_EndRequest(object sender, EventArgs e)
{
    ISession session = ContainerProvider.RequestLifetime.Resolve();
    //cleanup transaction etc...
    ContainerProvider.EndRequestLifetime();     
}

OR

• Create a session manager class that is IDisposable and lifetime scoped, take your ISession as a constructor dependency and do your session cleanup when it is Disposed at the end of the lifetime.

    public class SessionManager : IDisposable
    {
        private readonly ISession _session;
        private ITransaction _transaction;

        public SessionManager(ISession session)
        {
            _session = session;
        }

        public void BeginRequest()
        {
            _transaction = _session.BeginTransaction();
        }

        #region Implementation of IDisposable

        /// 
        /// Dispose will be called automatically by autofac when the lifetime ends
        /// 
        public void Dispose()
        {
            //commit rollback, whatever
            _transaction.Commit();
        }

        #endregion
    }

You must make sure to initialize your session manager.

    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        SessionManager manager = _containerProvider.RequestLifetime.Resolve();
        manager.BeginRequest();
    }

Add Modules to Web.config  Web Forms

The way that Autofac manages component lifetimes and adds dependency injection into the ASP.NET pipeline is through the use of IHttpModule implementations. You need to configure these modules in web.config.

The following snippet config shows the modules configured.

<configuration>
  <system.web>
    <httpModules>
      <!-- This section is used for IIS6 -->
      <add
        name="ContainerDisposal"
        type="Autofac.Integration.Web.ContainerDisposalModule, Autofac.Integration.Web"/>
      <add
        name="PropertyInjection"
        type="Autofac.Integration.Web.Forms.PropertyInjectionModule, Autofac.Integration.Web"/>
    </httpModules>
  </system.web>
  <system.webServer>
    <!-- This section is used for IIS7 -->
    <modules>
      <add
        name="ContainerDisposal"
        type="Autofac.Integration.Web.ContainerDisposalModule, Autofac.Integration.Web"
        preCondition="managedHandler"/>
      <add
        name="PropertyInjection"
        type="Autofac.Integration.Web.Forms.PropertyInjectionModule, Autofac.Integration.Web"
        preCondition="managedHandler"/>
    </modules>
  </system.webServer>
</configuration>

Note that while there are two different sections the modules appear in - one each for IIS6 and IIS7 - it is recommended that you have both in place. The ASP.NET Developer Server uses the IIS6 settings even if your target deployment environment is IIS7. If you use IIS Express it will use the IIS7 settings.

The modules you see there do some interesting things:

• The ContainerDisposalModule lets Autofac dispose of any components created during request processing as soon as the request completes.
• The PropertyInjectionModule injects dependencies into pages before the page lifecycle executes. An alternative UnsetPropertyInjectionModule is also provided which will only set properties on web forms/controls that have null values. (Use only one or the other, but not both.)
